comune-RANGE.

To all whom it 'may concern Y Beit known that I, DANIEL Boswonrtnot' the city, county, and State of New York, have invented a newV and useful Improvement in Cooking-Ranges, of

` which the following isa full, clear, and 'exact description, reference being had to the accompanying drawing forming part of vthis specification, andin which- Figure 1 represents a frontsectional elevation of a range f zonstructed.l inaccordance with my improvement, said `section being taken as indicated by the irregular' line 'v fc in Figure 2, which latter is a sectional elevation at right angles to g. 1`, being taken as indicated by the line 'w lw in Figure 4;

Figure is a similar view,'through thelinc :c x in p fig. 4, which latter is a sectional plan through `the line y y infigs. 2 and 3; i

Figure 5 is alsoa sectional plan,`through the line' 'z z; and

`I\`igure 6, aplan of the whole range. l

Similar'letters of reference indicate corresponding parts.4 l j y l f My invention, which is not only applicable to cooking-ranges, but also to cooking-stoves, when the same are providedwith 'anelevated oven or ovcns,'consists in a certain arrangement of a drop-flue between a pair ot adjacent elevated ovens, in combination with dues from the lire-chamber, arranged to communicate with said drop-flue at its top, andan outlet-pipe 'or ue in connection with it from below. By this arrangement `the heated products of combustion are restrained from ,too rapidly passing oft-in an upward direction, or

` checked asl-regards their ow past or around the Vovens, which secures amore electual heating of the l latter.

The invention-"likc'\vise includes a certain arrangenientof an air-pipe surrounding the smoke-pipe` and controlled by a damper, 'in combination with au aircasing arranged above the joven -or ovens, the whole serving to effect and controlthe heating of a body or current of air passing from below to a chamber or place above. l f

i Referring to the accompanying drawingfy A represents the fire-place or chamber of the range, the direct draughtfrom which is controlled bya damper, b, in rear of the re-place,so that, on opening said dampenvthe heated products 'of combustion may be passed oli` in a direct manner up a flue, B, `in free or open communication with 'the smoke-pipe G, or, by closing said damper, said products of combustion be diverted from the hre-place to opposite sides ofthe "iiue B, and up through ues D D, which connect at their tops with a iue or ues, E, arranged .to run under the bottom, over the back, outer side, and tops of elevated ovens F F, from whence the heated gases pass o'fi, by openings c c, intova space between the ovens, and which has a partition plate, (l, that makes of sa-id space'a drop-flue, G, in free communication below said partition with the smoke-pipe C. Y

By means of this dropflue,'i n combination with the nes with which it connects, the circulation ofthe dheated gases around the ovens is retarded, as it were,

or the products of combustion prevented from passing o too rapidly in an upward direction, thus securing a more perfect heating `ot' the ovens. n y

H isA an air-pipe, arranged to surround, or partially so, thev smoke-pipe O, and serving to convey heated air to a room or rooms above.

'Ifhis air-pipe is made to connect with anair-casng, I, situated over the ovens, and in communication, at its rear and sides or ends, with air-supply ues or passages c,at back and sides of the range, between the latter and the brick-'workin whichit is set.

J is a damper, arranged to control the air-pipe H.

'The air-casing I presents au ext-ended surface over thevovens, for the heating of the air in its way to the pipefH. ,f What is. here claimed, and desired to bev secured! by Letters Patent,fis--` y y 1.
